We’ve brought back the removable Inspiration Coin for 2021. The concept behind the design is the coin is meant to be paid forward to a person or group who helped inspire a runner to achieve their life goals, such as running a marathon. The coin has a magnetic backing. The race distance is revealed after the coin is removed.


Corrigan Sports Enterprises has been informed as of 6/9 at 4:00pm by the Wilmington Mayor’s office that the City of Wilmington Police Department does NOT have the necessary number of police officers to support the first 13 miles (within the city limits) of the Delaware Marathon Course.  Therefore we are sad to have to inform our Full Marathoners that we are going to have to cancel this Sunday’s Delaware FULL Marathon. 

The rest of the events will go on as planned on Sunday and use an alternate route.  The Half-Marathon. 5K and Team Relay (which will be modified to a 4-person relay completing 13.1 miles) will now primarily consist of the Riverfront area and the Markel Trail.  Start times for those races remain the same.  

Full Marathoners are welcome to join us for the half-marathon or receive a refund.  Please fill out THIS FORM to choose your option.

Corrigan Sports Enterprises worked very hard in the last 48 hours to avoid this conclusion, but to no avail.  Please know that the Corrigan Sports Enterprises team takes a great deal of pride in the production and execution of our events and we value the support of you the runners, our customer base.  We are very disappointed at the situation but are committed to making the best of a tough situation.  We appreciate your understanding during these trying times. 


Registrants must be 16 years of age and be able to complete the full 26.2 mile course in under 6 hours (13:44 min/mile pace).

Field Size

The marathon field will be capped at 1,000 runners, with a total of 3,000 runners in all events; although the Race Director reserves the right to change the size of the marathon field.


Online registration for the Delaware Marathon™ will close close June 11, 2021 at 11:59pm or earlier if the field is filled.  In-Person Registration will be available at the expo if space remains. Please register early as we have sold out in the past.

Once you have registered, please take the time to confirm the accuracy of the information. You may be able to look up and edit your information HERE.

If we are forced to switch to a virtual event, all participants will have the choice to run virtually or defer their entry to 2022. All virtual runners will receive their medal and UA race shirt in the mail.



2021 Marathon Course


The route for the 2021 Marathon will change slightly based on recent requests by the police and Riverfront Wilmington.  The route will continue to include much of the significant route updates that occurred in 2019, with a few minor adjustments. 

The marathon course will continue to run through some of the most scenic parts of downtown Wilmington and the routes unify the full, half and team relay courses so everyone uses the same routes for the first 13 miles.  The 2nd half of the full marathon course will continue to run along the recently completed Jack Markell Trail to New Castle Elementary School and back.  The trail offers some amazing scenery and will be stocked with 3 water stops and port-a-pots where access permits. 


Adjustments and changes might be made to the 2021 Full Marathon Course.


The course will consist of 14 water stops including 2 that you will pass in each in each direction on the Markell Trail and one at the turnaround at New Castle Elementary School.  Due to limited access points on the trail, we will offer full bottles of water at the stop at Mile 14.5, just at the mouth of the trail entrance.  This will allow marathon runners to carry a full bottle to supplement their hydration while on the trail.  Feel free to bring your own hydration system (such as a camelbak) if you prefer or to refill your bottle at the other water stations along the trail.

Each water station will also offer port-a-pots for runner use.  On the trail, where you will pass them in each direction we will offer additional units to alleviate congestion.

We will provide complementary HUMA Gel, the official race gel of the Delaware Running Festival at one location on the marathon course.
